MATTHEW J. DOLPHIN, OF BROOKLYN, NEW YORK.

INK-FEEDER.

SPECIFICATION forming part of Letters Patent No. 517,036, dated March 27, 1894.

Application led May 23, 1891. SerialNo. 393.860. (No model.)

.To all whom it may concern..-

Be it known that I, MATTHEW J. DOLPHIN, of Brooklyn, in the county of Kings, in the State of New York, have invented new and useful Improvements in InkFeeders, of which the following, taken'in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to an improved ink feeder, and has for its object the production of a simple, strong, durable and efficient device which elfects an even flow of the ink, and a positive regulation of the flow; and to this end it consists, essentially, in a suitable shell having au ink containing chamber pro vided with a pocket on its interior, a feeding opening or openings extending -from the'interior of the pocket to the outer surface of the chamber, and a partially revoluble adj uster foropening and closing said openings.

The invention furthermore consists in an adjusting rod having one extremity tapered, and seated in the pocket, in the chamber and the other provided with a hand-engaging portion, passages extending through the adjuster, and a spring mounted on the adjuster for forcing it into its normal position.

The invention still furthermore consists in the detail construction and arrangement of theparts, all as hereinafter more particularly described and pointed out in the claims.

In describing this invention, reference is had to the accompanying drawings, forming a part of the specification, in which, like letters indicate corresponding parts in all the views.

Figures 1 and 2 represent, respectively, side elevation and longitudinal vertical sectional views of my improved invention. Fig. 3 is a top plan view of the parts as illustrated in Figs. 1 and 2. Fig. 4 is a similar View to Fig. 3, the clamp for holding the cap of theinker cylinder in position being removed for the purpose of illustrating the ink inlet opening. Fig. 5 is a top plan View of the detached cyl-v inder. Fig. 6 is an inverted plan view of the cap for the cylinder. Fig. 7 is a sectional view, taken on line --.r-x, Fig. 2. Fig. 8 is an elevation of the detached lower extremity of the. adjuster; and Fig. 9 represents a modilied form of pocket.

This invention relates to the same class of inkers .set forth in my previous Patents Nos. 449,110 and 449,405, issued March 3l, 1891, and has for its 4object the production of an inker which is simpler in construction and an upwardly extending post -O-, the lower end of the post being hollow for the reception of a spindle, not illustrated, upon which the inker is supported in its revolution occasioned by suitable mechanism not illustrated.

-D- represents a removable cap for the shell -A- consisting of a round disk having an annular vertical shoulder -dadapted to enter the upper extremity of the chamber -aand an annular horizontal shoulder -CV- adapted to rest upon the top edge of the shoulder.

As best seen at Fig. 5, the upper edge of the shell ,-A- is formed with recesses or downwardly extending grooves -afor receiving lugs -dL- projecting from the cap D. At the center of the cap -D- is the ink inlet opening -D which is closed by a shoulder e formed upon the outer extremity of a clamp or thumb-screw -E- provided with a screw-threaded lower extremity -eadapted to enter a screw-threaded socket -c in the post -C- for retaining the cap in position and also permitting entrance of ink when the clamp is removed.

F represents a pocket provided within the shell -A- at one side of the lower extremity of the post -O and consisting, preferably, of a tube having a tapering central chamber -f-.

-G-G- are feeding openings extending from the interior of this pocket -F- to the outside of the shell -A- for permitting outlet or feeding of the ink.

-H- represents an adjuster partially revoluble for opening and closing the feeding passages G and permitting or restraining the liow of the ink. As preferably constructed, this adjuster consists of a rod having its lower extremity tapered and tightly seated within the tapered chamber -fof the pocket .--F= and its upper extremity provided with a handengaging portion h projecting to the outside of the shell A- and consisting, preferably, of a thumb-nut firmly secured to a shank formed upon the adjuster rod. As previously stated the shell -A- is revolved by-any suitable mechanism, as a frictionally engaging and positively driven roller, for feeding the ink by centrifugal force, and such is the tendency of the ink to feed from the roller that the adjuster must fit the pocket very closely and its adjustment be positive, minute and convenient, since the slightest-variation causes the marker to vary the character of its impression. Accordingly, to produce the desiredadj ustment, the lower extremity of the adjuster, as best seen at Figs. 2 and S, is formed with passages *IAT- adapted to register with the openings -G- and govern the feed of the ink by the degree of registration with said passages G-.

It will readily be perceived that as the rod -I'I- is partially rotated, the passages --H are moved into or out of registration with the openings G and in order to enable the operator to determine readily and positively the degree of adjustment required, the hand-engaging portion his provided with a finger 7i,- movable over an index -h2- best seen at Fig. 4. For rendering this adjustment more perfect, minute and certain, the extremities of the openings -H are formed with tapering slots or grooves H2- which gradually decrease in area, as best seen at Fig. 8.

It is evident that in order to obtain a practical adjustment of the adjuster, its lower extremity must tightly fit the chamber of the pocket -F and that it must also turn comparatively easy. To attain this result, the chamber -f and the lower extremity of the adjuster II- are made tapering and interposed between the shoulder -HB- on said adjuster and the adjacent face of the cap Dis a spring-I-which constantly forces said adjuster into its normal position.

At Fig. 9 I have shown, in cross section, a form of pocket which is only partially tubular, but it will be understood that this is no departure from my invention, since the lower extremity of the adjuster is suitably supported at h3 in the shell -A-, the inner wall of the tubular pocket may be dispensed with, provided the adjacent faces of the adjuster and remaining portion of pocket bear very closely against each other. I do not, however, regard this as the preferable construction, since even though it requires less material, it requires more careful workmanship.

'llle operation of my invention will be readly perceived from the foregoing description and upon reference to the drawings, and it is evident that the device is very simple, the supply of ink readily replenished by the removal of the clamp ME, and the flow of ink positively regulated by the adjustment of the adjuster or movable rod HH-M.

It is evident that the parts of my inker may be somewhat changed from those shown and described, hence I do not limit myself to the precise form and construction of the detail parts.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
